Fin Plate Shear Connection Calculator

Design bolted fin plate (single plate) shear connections per EN 1993-1-8. Eleven checks: bolt shear §3.6.1, bearing on fin plate and beam web §3.6.1, plate gross/net shear §6.2.6, block tearing (plate + web) §3.10.2, plate bending §6.2.5, fillet weld §4.5.3.2, beam web shear §6.2.6, and LTB slenderness (SCI P358). Live results — no sign-up required.
